To all whom it may concern:

Be it known that I, Josnrn RoMaNnY, a

citizen of the United States, residin at Harmarville, in the county ofAllegiieny and State of Pennsylvania, have invented new and useful Improvements in Insulators for Telephone and High-Tension Conductors, of which the following is a specificatio Q The object of my said invention is the -'provision of an insulator designed more particularly for telephone conductors, the said insulator being equipped with simple and easily manipulated conductor-gripping means, calculated to avert buzzing in a telephone due to a loosely held wire, and this in such manner that while there is no liability of the conductor becoming accidentally loose in the insulator yet when desired the conductor may be quickly and easily released from the insulator.

To the attainment of the foregoing, the

invention-consists in the improvement as hereinafter described and definitely claimed. In the accompanying drawings, forming part of this specification':'-

Figure 1 shows my novel insulator as holding a telephone conductor and as associated with the cross-arm of a telephone pole, said arm being in section.

Figure 2 is an elevation of the insulator per se and its appurtenances taken at right angles to Figure 1, the telephone conductor being in cross-section.

Figure 3 is a View, partly in elevation and partly in section, the section being taken in the plane indicated by the line 33 of Figure 2.

Figure 4 is a top plan view.

Figure 5 is an inverted lan view.

Similar numerals of re erence designate corresponding parts in all of the views of the drawings.

At 1 I show the cross arm of a telephone pole, in which is a slot 2 of dovetail form in cross-section, and in the preferred embodiment of my invention I prefer to provide the body 3 of my'novel insulator with a correspondingly-shaped base projection or anchor 4 to rest in said slot.

The insulator is formed in one piece of glass or other appropriate dielectric material, and in. addition to the body 3 and anchor 4 it comprises a head 5. At its upper corner the said head 5 is preferably rounded,

as designated by 6 and inits u per side the head is. provided with a di aimetrical depression 7, designed to seat a telephone conductor and after the manner shown' in Figures 1-4; the conductor being deflected at 9 and 10 as best shown in Figure 3. The said deflections 9 and 10 are ced apart and are pendent so as to rest in the com-.

paratively deep channels 11 which are formed in the up r side of the head 5 and intersect the epression 7. Manifestly when. the deflections 9 and 10 are held in the bottoms of the channels 11 endwise movement of the conductor 8 relative to the insulator will be recluded.

For holding t e conductor deflections 9 andlO in the bottoms of the channels 11 I employ a bail-shaped holder 12, hingedly and permanently conneetedto the head 5 by a pin 13 secured therein, and designed to rest in the channels 11. and having a pendent loop 14 disposed exteriorly of and adjacent to the periphery of the head 5 as ap ars in Figures 1 and 2. When the said ho der 12 is dlsposed as shown with its side bars in the depressions 9 and 10 of the conductor 8, it is detachably secured in such relation through the medium of a pin 15 removably sheathed in the head 5 and having a. fin r piece 16 at one end as best shown in igure 1. Obviously it is within the purview of my invention to have both pins 13 and 15 removable from the head 5 though I prefer to release the conductor 8 when necessary by withdrawing the pin 15 and then swinging the holder 12 on the pin It will be apparent from. the foregoing that notwithstanding the simplicity of my improvement and the facility with which it can be manipulated it is calculated to securely hold a telephone, high-tension or other conductor in such manner that casual loosening of the conductor will be precluded.

I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to implart a full, clear and exact understanding of the said embodiment. I do not desire, however, to be understood as confining myself to the specific construction and relative arrangement of parts inasmuch. as in the future practice fications may be made such as fall Within the scope of my invention as defined in my tip ended claim.

aving described my invention, what I claim and desire to secure by Letters Patent, is:-

An insulator having a head with a. diametrical depression to seat a conductor and also with comparatively deep channels intersecting the depression to seat pendent deflections of the conductor, in combination with a bailshaped holder hingedly connected to the insulator and having side portions for engagement Within the channels and a pendentbight end portion exteriorly of the insulator, and a keeper detachably arranged in the insulator above the free portion of the holder.

In testimony whereof, I afiix my signature.

JOSEPH ROMANDY.
